Description
Anordning for en- og tosidig bestrykning av papir. Device for one- and two-sided coating of paper.
Oppfinnelsen omfatter en mekanisk anordning for fremstilling av en- eller to-sidig be-strøket papir. En rekke forskjellige system har tidligere også være foreslått og brukt i fabrikk-skala, og en av de enkleste apparatene er limpressen som også vises i figur 2. Papirbanen fø-res her gjennom et nipp mellom to valser, den ene ofte fremstilt av stål og den andre av samme materiale, men med et belegg av hårdgummi. Den undre valse kan rotere i et bad med bestrykningsmasse som gjennom valsens rotasjon overføres til papirets underside eller også kan bestrykningsmassen som på papirets overside enten sprøytes på valsens overflate eller direkte på papirbanen. Limpressen kan anordnes med valsene montert med forskjellige vinkler mellom 0 og 90°, her betyr 90° at papirbanen føres vertikalt. The invention includes a mechanical device for producing one- or two-sided coated paper. A number of different systems have previously also been proposed and used on a factory scale, and one of the simplest devices is the glue press, which is also shown in figure 2. Here, the paper web is fed through a nip between two rollers, one often made of steel and the other of the same material, but with a coating of hard rubber. The lower roller can rotate in a bath with coating compound which, through the rotation of the roller, is transferred to the underside of the paper or the coating compound which is on the upper side of the paper can either be sprayed onto the surface of the roller or directly onto the paper web. The glue press can be arranged with the rollers mounted at different angles between 0 and 90°, here 90° means that the paper web is guided vertically.
Erfaringen har vist at en limpresse kan Experience has shown that a glue press can
gi et tilfredsstillende belegg ved lav hastighet provide a satisfactory coating at low speed
eller lav pålagt mengde bestrykningsmasse. Økes hastigheten eller bestrykningsmassens viskositet, opptrer dog den mønstring som ofte kalles «orange peel» og som er en ulempe fordi del ferdige trykkresultat på papiret blir dårlig. Denne mønstring beror sannsynligvis på kavi-tasjons- eller visko-elastiske fenomen som opptrer på den utgående side av nippet, og denne mønstring øker med økende viskositet eller økende kohesjon hos bestrykningsmassen. Geo-metrien i nippet er også av betydning og det er også kjent at valsediameter og avtagnings-vinkel spiller en viss rolle for resultatet. or low required amount of coating compound. If the speed or the viscosity of the coating material is increased, however, the pattern that is often called "orange peel" appears and is a disadvantage because the partially finished print result on the paper becomes poor. This pattern is probably due to cavitation or visco-elastic phenomena that occur on the outgoing side of the nip, and this pattern increases with increasing viscosity or increasing cohesion of the coating mass. The geometry of the nip is also important and it is also known that the roll diameter and take-off angle play a certain role in the result.
Hensikten med oppfinnelsen er å eliminere nevnte mønstring, og en skisse av systemet vises i figur 1. De tidligere nevnte limpressevalser er her anordnet ute av inngrep med hverandre, og mellom disse er det plasert en ytterligere valse med vesentlig mindre diameter enn de to hovedvalsene, fortrinnsvis med en diameter av fra 3 til 6", mens papirbanen fremføres mellom en av hovedvalsene og den nye valse i det nipp som dannes der. På denne måte oppnås at papirbanen kan fjernes mer abrupt fra valsene. En liten midtvalse er derfor gunstig bare i den grad den kombineres med en hensiktsmessig føring av papirbanen ut av nippet. Papirbanen skal fortrinnsvis følge den lille midtvalse, men oppfinnelsen spesifiserer ingen bestemt avtag-ningsvinkel, og en alternativ baneføring er også vist i figur 1. The purpose of the invention is to eliminate the aforementioned patterning, and a sketch of the system is shown in Figure 1. The previously mentioned glue press rollers are here arranged out of engagement with each other, and between these is placed a further roller with a significantly smaller diameter than the two main rollers, preferably with a diameter of from 3 to 6", while the paper web is advanced between one of the main rollers and the new roller in the nip that is formed there. In this way, it is achieved that the paper web can be removed more abruptly from the rollers. A small middle roller is therefore advantageous only in to the extent that it is combined with an appropriate guidance of the paper web out of the nip. The paper web should preferably follow the small central roller, but the invention does not specify a specific take-off angle, and an alternative web guidance is also shown in Figure 1.
Midtvalsen i den skisserte konstruksjonen C kan være av hårdgummi, stål eller annet pas-sende materiale. Valsedimensjonene kan variere fra R/15 til R/3, men som nevnt fortrinnsvis være 3 til 6" i diameter. Valsene A og B kan være normale limpressvalser både med hensyn til materiale og dimensjoner f. eks. to valser med diameter på 50 cm, den ene av stål og den andre av stål, men kledd med hårdgummi. Overvalsen A kan imidlertid være mindre enn valsen B. The center roller in the sketched construction C can be made of hard rubber, steel or other suitable material. The roller dimensions can vary from R/15 to R/3, but as mentioned preferably be 3 to 6" in diameter. The rollers A and B can be normal glue press rollers both with regard to material and dimensions, e.g. two rollers with a diameter of 50 cm , one of steel and the other of steel but lined with hard rubber.However, the upper roll A may be smaller than the roll B.
Midtvalsen skal kunne flyttes horisontalt avhengig av hastighet, baneføring og bestrykningsmassens sammensetning, både på inn- og utsiden av nippet. Det er en forutsetning at det hele tiden skal være fysisk kontakt mellom midtvalsen og valsene A og B. Som det fremgår av figur 1, skal valsene A og B rotere i samme retning og denne bestemmes av maskinoppstil-lingen mens valsen B roterer i motsatt retning. The center roller must be able to be moved horizontally depending on speed, path guidance and the composition of the coating compound, both on the inside and outside of the nip. It is a prerequisite that there must always be physical contact between the center roller and rollers A and B. As can be seen from Figure 1, rollers A and B must rotate in the same direction and this is determined by the machine setup, while roller B rotates in the opposite direction .
Eksempel. Example.
Som eksempel nevnes en oppstilling hvor valsene A og B er montert vertikalt over hverandre. Begge valser har en diameter på 50 cm, begge er laget av stål, men valse B er belagt med hårdgummi. Valsen C er laget av stål og har en diameter på 12,5 cm. Sentrum av valsen C ligger 4 cm til venstre for senterlinjen mellom A og B med føring av papirbanen fra høyre mot venstre. Papirbanen trekkes ut av nippet ved en vinkel på 15° i forhold til horisontalplanet. As an example, an arrangement is mentioned where the rollers A and B are mounted vertically above each other. Both rollers have a diameter of 50 cm, both are made of steel, but roller B is coated with hard rubber. The roller C is made of steel and has a diameter of 12.5 cm. The center of roller C is 4 cm to the left of the center line between A and B, with the paper web running from right to left. The paper web is pulled out of the nip at an angle of 15° in relation to the horizontal plane.
